Summary

This study is a clinical trial designed to assess the impact on influenza vaccination rates among people aged over 65 of a telephone text message recalling them to be vaccinated by their GP. Twenty-two GPs will be randomly selected in each arm (recall versus usual care, 1:1). Each GP will include a maximum of 210 patients by random selection from their patient list. A difference of 4 percentage points is expected between the two arms at the end vaccination campaign in the vaccination rate.

Detailed description

This is an open-label trial with 2 arms: an interventional or "recall" arm and a "usual care" or control arm. Cluster randomization at the physician level was chosen to avoid contamination within the same patients group. Physicians will be randomized at the start of the vaccination campaign in one of the two arms (1:1), and all patients eligible (with a maximum of 210 per doctor) to be vaccinated will be recalled or not, depending on their GPs arm.

Conditions

• Influenza Viral Infections

Interventions

Type	Name	Description
OTHER	Reminder	At mid-campaign, GPs in the interventional arm will recall their patients to be vaccinated via the reminder module Eo software * This recall will be carried out as follows: patients whose medical records include a number likely to receive telephone text messages will be recalled by this means Two generic messages that doctors can choose will be proposed by the call-back module integrated into the Eo medical software * In addition, the recall module will offer to send a postal letter with the same content as the text message to patients who do not have a mobile phone number in the business software but do have a postal address * The recall module will also provide the doctor with a list of patients who have neither a mobile phone number or a postal address, so that he can recall them to be vaccinated orally by landline telephone or in consultation when they next visit. The type of recall and the date of it will be notified in the medical file of each patient.
